Houston and Johnson missed the previous two days of practice; Houston with a hamstring injury and Johnson with a sore knee.

In previous weeks, the Lions have had instances where a player returned to the practice field on a Friday and still didn't play on Sunday. It happened with defensive tackle Nick Fairley, running back Reggie Bush and right tackle Jason Fox already this year, so we'll have to wait and see until Sunday and their pregame workouts to see if they can go or not.

Safety Glover Quin, who missed practice on Wednesday and was limited both Thursday and Friday with an ankle injury, is also listed as questionable.

Receiver Patrick Edwards (ankle) and Fox (groin), who have missed multiple games due to their injures, are listed as probable.
